This email from Sundays for Dogs is engaging and visually appealing! The subject line grabs attention, and the offer is clear. To amp it up, consider a more dynamic CTA like "Fetch 25% Off Now!" to encourage clicks. Adding a happy dog enjoying the food in the visuals could boost emotional appeal. A playful tone in the copy could also inject more personality. Overall, it's a strong email with just a bit more polish needed to make it shine!
